Who Postscript Is For
postscript is best for Shopify brands that want to build SMS as a primary marketing and customer service channel. It fits merchants who rely heavily on Shopify's database for deep behavioral segmentation and want pre-built automation flows specifically optimized for Shopify stores.
Who Postscript Is Not For
postscript is not for non-Shopify e-commerce stores running on alternative platforms like WooCommerce or BigCommerce. It is also not ideal for brands primarily using email marketing who want a combined email and SMS tool in a single application, as alternatives like Klaviyo SMS or Attentive work across platforms and bundle both channels together.
